OK, I did find info on this after doing a search (sorry should have done the search before asking).
However, I do have a question. Is it just the kids who do the silly stuff? It appears from other posts that the adults get into to it too. Do they all get into it? What happens if you don't, does it ruin it or anything? We have a 15 year old with us who I am sure would feel uncomfortable doing the goofy antics, yet might enjoy the tour and mystery portion. Would like to do this as a family but don't want to embarrass her. What do you think???
